DOOR FOR RAILWAY CARS.

Application filed July 22, 1924. Serial No. 727,479.

To all whom it may concern.

Be it known that I, Pnrrnn E. PETERSON, a

citizen of the United States, residing at- Salina, in theccounty of Saline and State of Kansas, have invented certain new and useful Improvements in Doors for Railway Cars, of which the following is a specific; tion. i i

This invention relates to improvemei'its in doors especially adapted for use in box cars.

Briefly stated, an importantobject of this invention is to provide a box car door co-n sisting ofa plurality of sections, the lowermost of which may be swung outwardly to permit of the discharge. of the grain hearing against the same whereby the pressure on the upper sections of the door is relieved.

A further aim of the invention is'to provide a sectional door for box cars which may be conveniently applied to a box car without substantially altering the construction of the car and without in any way decreasing the capacityor-usefulness ofthe car.

A further object is to provide a door for box cars which is ofhighly simplified con struction, durable win use, and cheap to manufacture.

Other objects and advantages will be apparent during the course of the following description.

In the accompanyingdrawings forming a part of this applicationand in which like numerals are employed to design ate like parts throughout the same,

Figure 1 is a perspective of the improved door applied and in closed position;

Fig.2 is a perspective of the door with the lower section in open position; 1

Fig.3 is a horizontal sectional view talmn on line 33 of Fig. 1; v

Fig; 4 is a horizontal sectional view taken on line l4t of Fig. 1; p

Fig. 5 is a vertical transverse sectional view through the door in its closed position;

Fig. 6 is a group perspective illustrating the means to support the door and the sev eral sections of the door.

1 In the drawing, wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numeral 5 designates one side wall of a box car and the numeral 6 designates an opening adapted to be closed by means of a door generally desig nated by the numeral 7.

The improved door consists of upper, in-

' tcrmediate and lower sections 8, 9 and 10,

" member 31 as illustratedgin Fig. 1.

respectively, the upper and intermediate sections being provided at their ends with straps 3 arranged in U-shaped formation to define hinge straps. connected. to the hinge bar 11. The hinge bar or tube 11 is mounted upon a vertical rod 12, the ends of which are extended angularly as indicated at 14 and are extended through the side of the car for connection with lock nuts 16. An eye bolt 18 receives the intermediate portion of the tube 11 and strengthens and reinforces the same and at the same time limits the downward movement of the upper section 8. I 7

The lower section of. the door is hingedly connected as indicated at 20 to the lower edge of the intermediate section 9 and the lower section may be swung outwardly to an approximately horizontal position as illustrated in Fig. 2 when it is desired to discharge the grain or any part of it. After the pressure on the upper sections 8 and 9 has been relieved as a result of the upward movement of the lower sectionlO, the upper sections may then be swung inwardly to open position.

The lowerv section 10 is provided at it ends with looking wings 22, the outer ends of which are extended beyond the end of the lower section and are adapted to engage the jamb strips 96 of the door. This feature of the invention is illustrated in Fig. 4 and it will be seen by reference to this figure that when the extended ends of the wings 22 are engaged with the jamb strips 26 the outward swinging movement of the lower section is prevented. Of course, the wings 22 are hingedly connected as indicated at 98 to the end of the door and have their inner ends slightly reduced and formed with openings 80 for the reception of a fastening t, More specifically, the ends of the wings 22 may be moved into overlapping relation so that the same may be securely held in their operative position by means of the lockingdevice 81. Th locking device 31 is in the nature of a loop carried by the lower section 10 and adapted to extend llllTOllgll the openings and subsequently receive a locking pin carried by a chain 33. However, when the wings 22 are in their operative positionsas illustrated in Fig. 1, the door is not prevented from moving inwardly, but the lower section is only prevented. from moving out wardly.

- case the edges of the door would be beveled.

Suitable catches or other fastening device-s maybe employed to hold the door inplace,

either open or closed.

1th re'l'erence to the foregoing description taken in connection with the accompanying drawii ig it will be seen that a grain ca door constructed in accordance with this invention may be quickly operated to dischargethe grain from the car andwhen is desired to load the car this may be done quickly also. The improved lower section ll) and the associated elements form a convenient means whereby the pressure onthe upper sections may be quickly relieved;

In carrying out the invention the jiamb' strips 26 may be provided on their inner sides with hooks or other means to engagethe terminal portions of the wings 22 to hold the same in their elevated positions Having thus described the invention, what is claimed is 1. A grain car door comprising a pair of sections,meanshorizontally hinging one of the sections to the other section, andiwings hingedlyconnected to the ends of one of the sections and extended beyond the ends of that section to provide stops to. limit the swinging movement of that sect-ion, the wings being provided with meanswhereby the same may be detachal'ily secured in an.

elevated position to secure the associated section iii an open position. i

2. A grain car door con-iprising a section,

a sn'ins iiw section horizontall hin 'ed to a 2'2: a

the inst-named section, wings pivoted to. the ends of the swinging section and extended beyond the same. to define stopsadapted to engage jamb strips, the inner portions of said wings being 'adaptedto. overlap, and ineansto hold the inner portions of the wings in overlapped position. s

3. A grain car door comprisinga section,

a swinging section horizontally hinged to,

the first-named section, wings pivoted to the ends of the swinging section and extended beyond the same to define stops adapted to engage jamb strips, the inner portions of said wings being adapted to overlap, means to hold the inner portions of the wings in overlapped position, and hlnge means to support the first-named seetionifoiymovement about a vertical axis, there being means to hold the wings in an elevated position whereby to hold the swinging section inits discharging position. I i

5. In a grain car door, the combination of upper, intermediate and lower sections, said lower section being horizontally hinged to the intermediate section, wings vertically hinged to the ends of said lower section, said wings being eX-tendedbeyond the lower section to engage the jamh strips of the grain car door whereby to limit the outward swinging movement of the lower section, the inner portions of said wings being adapted to overlap each other and being provided with openings, and a fastening device, carried by the lower section and. adapted to extend through said openings to lock said wingsvin overlapping position. V i

6. In a grain car door, the combination of upper, intermediate and lower sections,

said lower section being horizontally hinged to the intermediate section, wings: vertically hinged to the ends ofsaid lower section, said wings being extended beyondthc lower section to engage the, jalnb strips off the grain car door whereby to. limit the outward swinging movement of the lower section,thc inner portions of said wings being adapted to overlap each other and being provided with openings, a fastening device carried byfthe lower section and adapted to extend tln'ongh IOU said openings to lock said wings in overlap pin-g position, and means. to, support the intermediate and upper sectionsformovement about a vertical axls. a i i In testimony whereof I allix niysignatnre.
